Abstract
The invention discloses a neodymium-iron-boron-hydrogen tank breaking cooling system. The neodymium-iron-boron-hydrogen tank breaking cooling system comprises a cooling bag, a gas output pipeline and a cooling device, wherein a gas input pipeline is arranged at the upper end of the cooling bag, and an air outlet hole is formed in the lower end of the cooling bag; the gas output pipeline is arranged on the upper portion of a hydrogen breaking tank; the cooling device is connected in series with the gas input pipeline and the gas output pipeline, and is used for refrigerating high-temperature gas exhausted from the gas output pipeline and conveying the high-temperature gas back into the hydrogen breaking tank through the gas input pipeline to realize circular refrigeration of neodymium-iron-boron powder in the hydrogen breaking tank. The neodymium-iron-boron-hydrogen tank breaking cooling system is simple and reasonable in structure. Argon gas is taken as a cold medium, and circulates in the hydrogen breaking tank through the cooling device to be directly contacted with the neodymium-iron-boron powder in order to refrigerate circularly. Gas is circularly and directly contacted with a product to perform contact refrigeration, and the conventional water cooling system is replaced, thereby realizing high cooling efficiency. Moreover, oxidation or discarding of neodymium-iron-boron powder due to the phenomena of cracks, even water seepage and water leakage on a cold water bag of the conventional water cooling system can be avoided.
Description
Technical field
The present invention relates to the broken tank of hydrogen field, particularly the broken tank cooling system of a kind of neodymium iron boron hydrogen.
Background technology
At present, neodymium iron boron hydrogenation crush method (being called for short hydrogen broken) is that NdFeB material is inhaled hydrogen generation lattice dilatation and emits heat, and in the process expanding, internal stress makes neodymium iron boron crystal intercrystalline fracture or becomes loosening body, thereby reaches the object that hydrogen is broken.Break once in journey and also have dehydrogenase/reductase refinement particle diameter except inhaling hydrogen at hydrogen, when dehydrogenation, in the broken tank of hydrogen, temperature can be elevated to 500 degree left and right along with heating, carries out afterwards cooling.
The broken tank of existing hydrogen is cooling air-cooled, two kinds of methods of water-cooled.Air-cooled: broken hydrogen cooling needs tank heating furnace door to be opened, started further electric fan and blow cooling to the broken tank of hydrogen.Water-cooled can be divided into two kinds, and one is, in the broken tank of hydrogen, a water coolers is set, and connects further recirculated water and carries out water-cooled.Another kind is broken hydrogen tank to be hung out in heating furnace to directly to put into cooling water cooling, or breaks tank with cool water shower hydrogen and reach cooling object.Also can apply as required in process of production air-cooled and water-cooled carries out cooling simultaneously.
The deficiency of following two aspects of the broken cooling existence of tank of existing hydrogen; When first water-cooled, cooling water circulation conduction cooling indirectly, makes cooling the spent time long, causes the makespan of powder long, and turnover slowly, affects quality and the production and processing efficiency of product; It two is suddenly to converge because cold water bag is often subject to high-low temperature difference, likely makes for a long time the cooling existing crackle drainage that even seeps water that contracts out, and can cause like this in the broken powder oxidation of neodymium iron boron hydrogen of system or scrap.
Summary of the invention
The present invention is in order to overcome defect in above-mentioned prior art, provide a kind of simple and reasonable, cooling effectiveness is high, and that can avoid existing water-cooling system coolingly contracts out the existing crackle drainage that even seeps water, and causes at the broken powder oxidation of neodymium iron boron hydrogen of system or the broken tank cooling system of neodymium iron boron hydrogen of scrapping.
